Look at the report generated by the software and find the iron concentration in each of your dissolved cereal samples.
Calculate the mass percentage of iron in each original cereal sample. Check for outliers, then compute an average and standard deviation that excludes any outliers.
The suggested serving size for this cereal is 30 g. The recommended daily allowance (USRDA) for a 20-year-old woman is 18 mg of iron. For a 20-year-old man, it's 8 mg. What percentage of the USRDA is included in a single cereal serving for both 20-year-old women and men?
